MACHINE FOR SEWING SWEAT-"BANDS [IN HATS.

Specification of Letters Patent. u afion fil d June 24,1905. sum-N0. 266,793.

Patented May 29, 1906,

I ing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented a certain new and useful Im rovement in Machines for Sewing Sweatands in Hats, of which the following is a full, clear, and exact description.

This invention relates more particularly to machines for sewing sweat-bands into stiff, felt, or other hats having aroll brim, although it may be used on other sewing-machines, if desired.

The object of the invention is to provide more convenient means for placing theiiat in and out of sewing position.

In the present invention is provided means which permits the operator to turn the front portion or head of the overhanging arm and its attached parts out of a vertical line or to one side of its operative position and without disconnecting any of the operative parts, the lowering and raising of the presser-bar acting to lock and unlock the head relatively to the fixed portion of the overhanging arm, all as will now be described and finally pointed out particularly in the claims.

In the accompanying drawings, illustrat ing the invention, in the several figures of which like parts are similarly designated, Figure 1 is a front side elevation of a hatsweat sewing-machine, the work-support in section and the sewing-machine base and overhanging arm partly in section. Fig. 2 is a front end elevation, the face-plate'beingre- .moved to expose the parts located in the front end of t e overhanging arm. Fig. 3 is a front end view of. the overhanging arm shown in Fig. 2 with head portion turned to one side of its vertical or operative position. Fig. 4 is a rear side elevation of the front portion of the overhanging arm. Fig. 5 is a perspective view of the feed-dog-actuating mech anism. Fig. 6 is a front elevation similar to Fig. 3, but with the needle-bar and presserbar removed.

1 is a supplemental base, upon which the sewing-machine base 2 is secured by a suitable hinge-joint 3, latch 4, and catch 5.

6 is the work-support, 7 the overhanging arm, and 8 the arm-standard, said base 2,

work-support 6, arm 7, and standard 8 c0mprising a single casting.

9 is the lower main shaft; 10, the bandwheel; 11, the shaft-flange; '12, the shaftflange stud; 13, the loop-taker '14, the looptaker driver; 15, the loop-taker-driver shaft; 16, the loop-taker-driver shaft-crank, and 17 the shaft-crank stud.

18 is the variable-motion link, the opposite ends of which are mounted upon studs 12 and 17, respectively, thus operatively connecting the lower main shaft 9 with the looptaker-driver shaft 15.

19 is the take-up cam, s'ecured'to the lower main shaft 9; 20, the'take-up rocker 21, the take-up-rocker stud, and 22 the take-uplever.

23 is the knurled head of a screw-24, tap ed in an arm 25 of a bell-crank lever 26, whic is fulcrumed in a bearing 27 in the base 2. To

the other arm 28 of said bell-crank lever is.

'30 is pivotally attached to a crank 33, secured to a feed rock-shaft 34, mounted in suitable bearings and 36 on thebase and work-support. The forward end of the feed rock-shaft is provided with a crank 37, to one end of which is secured alink 38, which is piv otally secured to a lug 39 on the feed-dog-carrying bar 40. To this bar 40 is adjustably secured by a screw 41 the feed-dog 42 for feeding the hat to the action ofthe needle 43. A second feed-dog 44 is adjustably secured by a screw 45 to an extended portion 46 of the feed-dog-carrying bar 40, said feed-dog being located at the rear side of the looptaker 13' and operated to advance the sweatband synchronously with the feed of the hat.

Vertical movements are imparted to the feeddogs 42 and- 44 by an eccentric 47 on shaft 9, coacting with a forked lever 48, secured on a lift rock-shaft 49, mounted between pintlebearings 50 and 51,'tapped in bearings 52 and 53in the base 2 and work-support 6.

On'the lift rock-shaft 49 are two lugs 54 and 55 between which is secured by pintlescrews ,56 and 57 the feed-dogcarrying bar 40, so that by the action of eccentric 47 vertical movements are given theI-feed-dog through the connections pointed out, and by eccentric 31 through the connections ointed out feed movements are transmitte to the feed-dog.

58 is the throat-plate, secured by screws 59 to the work-su port 6.

60 is the bob in-case, mounted in the usual manner in the loop-taker 13 and held against accidental displacement by the latch 61.

The. edge gages (shown in Fig. 1) are common to the Wheeler & Wilson hat-sweat sewing-machine, and the same is true of all the parts 1 to 61, inclusive, hereinbefore referred to, with the exception of the overhanging arm 7.

Referring to the improvements, 62 is a bushing adjustably secured by screw 63 in the front end of the overhanging arm 7 and provided with a flange 64, which enters a seat 65, formed in a swinging head 66, which head is thereby pivotally mounted upon said bushing 62. By the lengthwise adjustment of the bushing 62 the face 67 of the overhanging arm and the face 68 of the swinging head are held in adjustment relatively to each other, so that the, head 66 may be swung upon the bushing 62'without lost motion between the faces 67 and 68.

69 is a hand rock-shaft mounted at its forward endin the bushing 62, its opposite end mounted in abearing 70 in the overhan ing arm. The forward end of said rock-shaft is provided with a lever 71, through one end of which passes loosely a screw 72, tap ed in the wall 73. of-the swinging head 66, an at its oposite end shaft 69 is provided with a handever74, so that the operator may turn the head 66 out of operative position, as in Fig. 3, and return it to its operative position, as in Figs. 1, 2, and 4.

and 77, suitably secured in the swinging head 66, the lower end of said bar being provided with a needle-bracket 78, in which is secured the needle 43.

' 79 is the needle-bar rock-shaft, mounted in suitable bearings in the overhanging arm '7 and provided with a lever 80, which is pivotally attached to a link 81, the opposite end of said link being pivotally mounted upon a stud 82, having a collar 83, secured by screw 84 to the needle-bar 75, thus operatively connecting the needle-bar with the rock-shaft 79. To the rear end of the rock-shaft 79 is secured a crank 85, connected by an eccentricrod 86 with an eccentric 87, fast on the lower main shaft 9, thus operatively connecting the lower main shaft 9 with the needle-bar 7 5;

88 is the resser-bar, mounted in the bearings 89 an 90, the former being adjustable, so as to compress more or less the spring 91, encircling the presser-bar, so as to adjustably control the amount of pressure given the presser-foot 92 upon the material.

93 is the presser-lifter collar, secured by screw 94 to the resser-bar and provided with two arms 95 and 96, the former acted upon by the presser-lifter 97 to raise the presser-foot above the material, the free end of the second arm 96 acting upon a pin 98 secured in a bell-crank lever 99, the short arm of which bell-crank lever is pivotally secured by screw 100 to the swinging head 66, its longer arm entering a notch 101, formed in a bolt 102, which latter is mounted in a pocket 103, formed in the inner wall of the rear side of the swinging head 66, which bolt acts to lock theswinging head to the face 67 of the overhanging arm by the end of the bolt passing into ,a suitable hole 104. The opposite end of the bolt is acted upon by a spring 105, secured by screw 106 to hold said bolt in looking position.

107 is a collar secured by screw 108 on the presser-bar and provided with an arm 109, which extends upward and at its free end 1 10 is beveled to coact with the plunger 111, which plunger acts against the tension-disk 112 of the tension mechanism, so that when the presser-bar is lifted the beveled free end 110 of the arm 109 will force the plunger 111 againstthe'tension-disk 112 in opposition to the resiliency of the tension-spring 113, thus releasing the tension from the needle-thread. This tension and tension-releasing mechanism is substantially the same as is common to Wheeler & Wilson sewing-machines generally.

Referring more particularly to Fig. 4, 114 is a bracket secured by screws 115 to the swinging head 66, and 116 is an adjustable stop secured by screws 117 to the overhanging arm 7. This stop has two lugs 118 and 119,-the former acting to limit the swinging movement of the head 66 when moved into 'inoperative position and the latter acting to 75 is a needle-bar mounted in bearings'7 6 register the head in its operative position, so that the bolt 102 will enter the ole 104 and lock the swinging head to the face 67 of the overhanging arm 7.

120 is a bracket constructed with a pinchjoint and secured by a screw 121 to the resser-bar 88, the free end of the bracket be ing forked to embrace the bearing 76 to prevent axial movement of said resser-bar.

The operation is as follows: Supposing the work to be of such nature that an excessive clearance is desirable between the throatplate 54 and cloth-presser 92as, for instance, in the placing and displacing of a hat having a heavy roll stiif brimthe operator by lifting the presser-bar causes the arm 96 to act upon the pin 98, secured in the bellcrank lever 99, thus rocking said lever on its pivot-screw 100 and through its connection with the bolt 102 causing said bolt to be withdrawn from the hole 104, leaving the swinging head 66 free to be swung out of operative position on the bushing 62 by the manipulation of the hand-lever 74 or by the direct action of the hand upon the swinging head. The head is returned in like manner to its operative position, the lowering of the presser-bar permitting the bolt 102 to again lock said head in its operative position.

By referring to Fig. 3 it will be seen that the axis of the stud 82 when the head 66 is adjusted to its ino erative position is substantially in line wlth the axis of the hand rock-shaft 69, thus permitting the head to be swung in opposite directions without materially changing the position of the needle-bar, thus holding the needle-point guarded by the clothresser against injury.

What claim is- 1. In a sewing-machine, an overhanging arm provided with a swinging head, a needle bar-actuating shaft mounted in said arm, a needle-bar and a presser-bar mounted in said head, and connections between said needlebar-actuating shaft and needle-bar, in combination with a locking device operatively connected with the presser-bar for securing said head against accidental movement when adjusted to sewing position.

2. In a sewing-machine, a work-support, an overhanging arm, a head pivoted to said arm, a needle-bar and acpresser-bar mounted in said head, a horizontal rock-shaft mounted in the overhanging arm and provided with a hand-lever at one end and connected With said pivoted head at its other end and adapted to rock said head on its pivot to throw the needle-bar and presser-bar to one side of the work-support, an automatic locking device for locking the head to the arm in its sewing to said arm, a needle-actuating shaft and connections between said needle-bar and its actuating-shaft, a loop-taker connected with the main shaft and connections between said main shaft and needle-actuating shaft, a locking device carried by said adjustably-secured head and connected with the presserbar, and stops for limiting the movements of said swinging head in opposite directions.

4. In a sewing-machine, a Work-support, an overhanging arm, a head pivoted to said arm, a needle-bar and a presser-bar mounted in said head, means to rock said head on its pivot to throw the needle-bar and presserbar to one side of the work-s11 port, an automatic locking device for locking the head to the arm in its sewing position, and means actuated by the presser-bar to unlock the looking mechanism to permit the head to be swung out of sewing position.

In testimony whereof I have hereunto set my hand this 20th day of June, A; D. 1905.
